Detailed Description
Insulating Glass:
Insulating glass is a kind of glass product with a drying air space. It is composed of two or more pieces of glass as effective support and partition and uses a seal around the edges. The glass is partitioned with hollow aluminum alloy bulkhead filled with desiccant or compound seal string, and the cavity layer is filled with dry air or inert gas. The bulkhead and glass are sealed with butyl adhesive before the treatment with polysulfide sealant or structural sealant. Insulating glass can be categorized into two-layer and multilayer insulating glass according to the number of cavities. The former is composed of two pieces of plate glass and one cavity, and the latter is composed of more than two pieces of glass and two or more cavities. The more the number of cavities, the better the thermal and acoustic insulation will be. The two-layer and three-layer insulating glass with two cavities are most widely used.
The bulkhead embedded insulating glass and blind insulating glass developed by our Company are composed of pieces of glass with various artistic patterns and embedded with bulkheads or blind of various materials. It can provide good features of energy conservation, decoration and privacy protection. It can be widely used in glass curtain walls, doors and windows of industrial and civil construction, the glass parts of automobiles, trains, ships, aircrafts and instruments, and the places that require thermal insulation and temperature control and dew control, such as observation door of freezers and cold storages, to prevent frost and heat transmission.
 
 
 
Product Varieties:
We can provide various insulating glass products in different shapes that meet different energy-saving requirement by using any flat glass (including float glass, coated solar control glass, low-e coated glass, colored glass, laminated glass, tempered glass, hot bent glass or self-cleaning glass) according to the requirements of customers, such as safe and decorative bulkhead embedded insulating glass, blind insulating glass, tempered insulating glass, low-e insulating glass, laminated insulating glass, hot bent insulating glass, automobile insulating glass, instrument peephole insulating glass and home appliance insulating glass.
Features:
·       It can meet the requirements on lighting, scenic, decorative and environmental protection, and solve the issues of the comfortable and beautiful living environment and noise control.
·       It has good thermal insulation: it can effectively prevent outdoor heat into the room in summer and prevent interior heat loss in winter, reducing air conditioner fees and saving energy, as shown in Table 2-2.
·       Excellent temperature tolerance, heat resistance, moisture resistance, cold resistance, frost resistance and dew resistance.
·       The insulating glass made of self-cleaning glass has a number of special features: water affinity, mildew proof, deodorizing, degrading organic pollutants, decomposing harmful gases and purifying the air.

Acoustic Insulation of Insulating Glass
The loudness of sound is measured in decibels (dB). The noise of 60 decibels (dB) will make people uncomfortable; the noise of 80 decibels (dB) will irritate people; the noise of 90 decibels (dB) may cause hearing impairment and the noise of 120 decibels (dB) is out of the normal range of the senses. Standard of environmental noise of urban area is shown in Table 2-3.

4 in ① presents that the glass thickness is 4mm; 12A presents that the spacer layer is a 12mm-thick air layer.
The acoustic insulation of insulating glass is associated with the thickness and the area of the spacer layer, and the greater the thickness and area, the better the acoustic insulation will be. By increasing the thickness and area of the spacer layer, the acoustic insulation of insulating glass will be improved. In addition, the two-layer or multilayer insulating glass composed of the glass and spacer layer of different thickness can effectively improve the acoustic insulation.
Statistics show that a single piece of glass can reduce noise by 20~22dB and two-layer insulating glass by 29~30dB. In order to improve the acoustic insulation of insulating glass, the usually adopted method is to use the glass substrates which are asymmetrical in thickness, fill the spacer layer with dry inert gas or use laminated glass as the substrates to take advantage of the acoustic damping effect of PVB film. By adopting the above method, the acoustic insulation of insulating glass can be up to 45dB.
Dew Prevention of Insulating Glass
The air in insulating glass is dry due to the inside desiccant adsorbing water molecules, and no dew is formed in insulating glass as the temperature decreases, and it can increase the dewpoint of the outer surface. For instance, when the outside wind speed is 5m/s, the indoor temperature 20°C and the relative humidity 60%, dew is formed on 5mm glass when the outdoor temperature is 8 °C, while dew is not formed on 16mm (5+6+5) insulating glass until the outdoor temperature is -2°C under the same conditions, and dew is not formed on 27mm (5+6+5+6+5) three-layer insulating glass until the outdoor temperature is -11°C.
